Forecast Discussion: Current Conditions: As of 2 PM on Monday, partly sunny skies prevail over the region as high pressure continues to control our weather. Right now, the center of the high is situated over the Tennessee and Ohio River regions. The location of the high near our area has allowed the winds to die down. The sunshine this afternoon has forced temperatures into the low 80s. In addition, dewpoint temperatures are hovering in the mid 60s. The combination of the seasonably warm and humid air has forced PM 2.5 levels to rise into the moderate threshold. The cloud cover is still helping to hold ozone concentrations in the good category. Expect the moderate air quality to continue into tomorrow as high pressure remains the prominent weather feature over our area. *** Tuesday's Forecast: So for Tuesday, mostly sunny skies will persist throughout the day as the area of high pressure, which was off to our west on Monday, moves off to our east. As a result, our winds should turn more out of the south, resulting in warmer air moving northward into our region. In fact, afternoon temperatures will range in the upper 80s. It will remain humid as well. Therefore, expect PM 2.5 levels to continue to range in the moderate category. Ozone concentrations are going to thrive in the sunny environment and reach the moderate range as well. *** Extended Outlook: Over the coming days, expect to see temperatures remain at to below normal as a series of storm systems move through the region. Here is how things are shaping up... On Wednesday, expect more clouds to roll into the region as a cold front, which pushed in over the Great Lakes on Tuesday, pushes through our area. As it moves through, expect the threat of showers to increase. Once the front passes through, a new area of high pressure will build in over the Midwestern US, steer our flow out of the north and deliver a cool and dry air mass over our area. As a result, Thursday and Friday's highs are only expected to get into the upper 70s. Good air quality is likely as well. This high will be slow to move off to our east. Once it does (by next Monday, a new storm system will begin to push into the region. Overall, expect air quality levels to be at their highest over the upcoming weekend as a combination of more sunshine and more seasonable temperatures forces ozone and PM 2.5 concentrations to rise. --Nolan
